Police reported three people were injured in the shooting, which occurred around 6:30 p.m. inside a common area in the mall just outside of Target. Thursday morning, police confirmed a fourth person was injured when she fell while running away from the scene.

According to an official on the scene, a man was taken to Methodist Hospital in critical condition. Another man and a woman were taken to Eskenazi Health with non life-threatening injuries. All three victims are now in stable condition, police said.

Police say the suspect, still at large, knew one of the victims. The suspect had an altercation with that victim before shots were fired. The other two victims may have been innocent bystanders.

All three of the victims were young adults.

Police said there were no signs of gang-related activity.
